Product details
Overview
TLV2475AIN from Texas Instruments is a quad-channel, rail-to-rail input/output CMOS operational amplifier with shutdown functionality, 2.8MHz gain-bandwidth product, 600μA per channel supply current, and ±35mA output drive at 500mV from rails - designed for low-voltage sensor interface and portable medical equipment.
For engineers reviewing the TLV2475AIN datasheet, TLV2475AIN pinout, TLV2475AIN application, or TLV2475AIN equivalent, key selection considerations include its 16-pin TSSOP package, shutdown current of 1000nA/ch at 5V, rail-to-rail swing capability, and guaranteed operation across –40°C to +125°C industrial temperature range.
Technical Context
The TLV2475AIN implements a CMOS input stage enabling 2.5pA typical input bias current and rail-to-rail common-mode input voltage range (0V to VDD). Its output stage delivers ±35mA into loads while maintaining rail-to-rail swing within 500mV of supply rails under heavy load.
Shutdown control is implemented via dedicated SHDN pins (pins 3/4) that place outputs in high-impedance state and reduce supply current to 1000nA per channel at 5V. The device is fully specified at both 3V and 5V single-supply operation across the extended industrial temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 2.8MHz - supports stable unity-gain buffer and closed-loop amplification up to ~200kHz with 10x gain. |
| Supply current per channel | 600μA at 5V - enables multi-channel signal conditioning in battery-powered systems with minimal quiescent power impact. |
| Shutdown current per channel | 1000nA at 5V - reduces total system standby power to sub-microamp level when channels are disabled. |
| Output drive capability | ±35mA at 500mV from rail - drives 10kΩ loads to full rail while sourcing/sinking >30mA for active filtering or transducer excitation. |
| Input offset voltage | 250μV typical - ensures <1mV total error in precision DC-coupled gain stages with gains ≤4. |
| Supply voltage range | 2.7V to 6V - compatible with single-cell Li-ion (3.0–4.2V), 3.3V logic, and dual AA/AAA (3.0V nominal) power domains. |
| Rail-to-rail I/O | Full swing input and output - maximizes dynamic range in low-voltage ADC front-ends and sensor signal chains. |
Pinout & Package
The TLV2475AIN is housed in a 16-pin TSSOP (PWP) package with 0.65mm pitch, 5.0mm × 4.4mm body size, and exposed pad for thermal enhancement. Pin 1 is marked by a beveled edge or molded dot.

| 1IN− | Channel 1 inverting input | Differential input terminal; rail-to-rail common-mode range (0V to VDD). |
| 1IN+ | Channel 1 non-inverting input | Differential input terminal; supports direct connection to grounded sensors or reference voltages. |

| 3OUT | Channel 3 output | Output node for third op-amp; identical drive and rail-swing specs as 1OUT. |
| 3/4SHDN | Shutdown control for channels 3 & 4 | Active-low logic input; pulls high internally; must be driven ≤0.8V to activate shutdown mode. |
| 4OUT | Channel 4 output | Output node for fourth op-amp; shares same electrical characteristics as other outputs. |
| 4IN− | Channel 4 inverting input | Differential input for channel 4; rail-to-rail input stage enables direct interfacing with low-voltage sources. |
| 4IN+ | Channel 4 non-inverting input | Non-inverting input for channel 4; supports unity-gain follower configurations without external biasing. |
| VDD | Positive supply rail | Single supply input (2.7–6V); powers all four amplifiers and internal bias circuitry. |
| 2IN+ | Channel 2 non-inverting input | Input for second amplifier; independent of other channels for multi-sensor signal conditioning. |
| 2IN− | Channel 2 inverting input | Inverting input for channel 2; supports standard inverting amplifier topologies. |

| 1/2SHDN | Shutdown control for channels 1 & 2 | Active-low logic input; independent of 3/4SHDN to enable selective channel disabling. |
Key Features

| Rail-to-rail input and output | Enables full utilization of 2.7–6V supply range in single-supply data acquisition, maximizing SNR and dynamic range. |
| 600μA per channel quiescent current | Supports always-on sensor monitoring in portable devices while limiting total quiescent draw to <2.5mA for all four channels. |
| Dual independent shutdown controls | Allows partial system power-down (e.g., disable unused channels during sleep mode) without reconfiguring PCB layout. |
| ±35mA output drive at 500mV from rail | Drives 10kΩ loads to full rail and supports active RC filters, transducer excitation, and LED biasing without external buffers. |
| 2.5pA typical input bias current | Minimizes voltage error in high-impedance sensor interfaces (e.g., pH electrodes, piezoresistive bridges) without guard traces. |
| Specified from –40°C to +125°C | Validates performance in automotive cabin modules, industrial motor controllers, and outdoor environmental sensors. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2475CDR | Same silicon, commercial temperature range (0°C to +70°C), SOIC-14 package, no shutdown function. | Lacks independent shutdown controls; unsuitable for battery-critical designs requiring partial channel disable. | Select TLV2475CDR only for cost-sensitive, non-portable applications where full-temperature-range operation and shutdown are unnecessary. |
| OPA4340UA | Fully rail-to-rail I/O, 5.5MHz GBW, 750μA/ch supply current, no shutdown, SO-14 package. | Higher bandwidth but no shutdown; higher supply current increases battery load; different pinout prevents drop-in replacement. | Choose OPA4340UA when bandwidth >2.8MHz is required and shutdown is not needed; verify PCB layout compatibility due to different pin mapping. |
Compared with TLV2475CDR and OPA4340UA, the TLV2475AIN uniquely combines extended temperature range (–40°C to +125°C), dual independent shutdown controls, and 16-pin TSSOP packaging - making it the only option among the three qualified for automotive cabin modules and industrial field transmitters requiring robust thermal performance and selective power management.

FAQ
What is the operating temperature range for the TLV2475AIN?
The TLV2475AIN is rated for operation from –40°C to +125°C, meeting industrial and automotive under-hood requirements. This extended range is confirmed in the Absolute Maximum Ratings and Recommended Operating Conditions tables of the official TI datasheet SLOS232E, and applies across all electrical specifications including input offset voltage, supply current, and output drive capability.
Does the TLV2475AIN support true rail-to-rail input and output operation?
Yes, the TLV2475AIN features CMOS rail-to-rail input and output stages. Its input common-mode range extends from 0V to VDD, and its output swings within 180mV of each rail at ±10mA load - or within 500mV while delivering ±35mA. These values are measured and guaranteed in the Electrical Characteristics tables for both 3V and 5V supply conditions.
How many independent shutdown controls does the TLV2475AIN have, and how do they work?
The TLV2475AIN has two independent active-low shutdown controls: pin 1/2SHDN disables channels 1 and 2, while pin 3/4SHDN disables channels 3 and 4. When pulled ≤0.8V, each control places its associated amplifier outputs in high-impedance state and reduces supply current to 1000nA per channel at 5V. Both controls are internally pulled high and require no external pull-up resistors.
What package type is used for the TLV2475AIN, and what are its key mechanical features?
The TLV2475AIN uses a 16-pin TSSOP (Thin Shrink Small Outline Package), also designated PWP by Texas Instruments. It measures 5.0mm × 4.4mm with 0.65mm lead pitch and includes an exposed thermal pad. Pin 1 is identified by a beveled edge or molded dot, and the package is RoHS-compliant and halogen-free per TI's packaging standards.
Can the TLV2475AIN drive capacitive loads, and if so, what is the recommended compensation method?
Yes, the TLV2475AIN can drive capacitive loads, but for loads exceeding 10pF, TI recommends adding a series null resistor (RNULL) between the output and the load - typically ≥20Ω - to maintain phase margin and prevent oscillation. This configuration is documented in Figure 42 of the datasheet and validated across temperature and supply voltage ranges.
